ATH-PRO500MK2RD vs. ATH-M50 (sound quality)?

Are the highs and mid-range sounds of the ATH-PRO500MK2RD equal/better to that of the ATH-M50? I'm not a DJ, I just love the look of the ATH-PRO500MK2RD. I like folk music, so I just want to be sure that the bass won't completely overshadow the highs and mids of some the other genres I listen to. In short, is the ATH-PRO500MK2RD close to the ATH-M50 except with better bass? And will the enhanced bass muddy-up the more delicate highs and mids of the songs I listen to recreationally?

Personally I think for folk music you'd be better served using the m50's I have the m50 and the ATH-PRO700MK2.
